Can they prescribe painkillers for headaches?

I've had chronic headaches for about four or five years. Nothing helps. I've tried so many things (acupuncture, chiropractor, yoga, allergy testing, medications (Depakote, propranolol, Topamax), got an MRI and CT scan and I don't have any tumors or anything. OTC stuff doesn't help at all. I've tried tylenol, advil, excedrin (extra strength and tension headache), sudafed sinus congestion, afrin nose spray, aspirin, zyrtec (I take that every day). For the past month or so, they've been getting worse (that's happened before, they were really bad for a while). They've really impacted my life. I don't really go out with friends anymore because I just wanna stay home and rest and no one really asks me to anyway because I don't seem as outgoing anymore (although, I wasn't all that outgoing to begin with). I don't want to do homework, I procrastinate. I never used to do that though, procrastination is weird for me. So, can the doctor prescribe me some painkillers or something?
